BUTTON AND BUTTON -FASTENER.

SPECIFICATION forming part of Letters Patent No. 301,269, dated July 1,188%.

- Application filed April '7, 1884. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS PORTER, of Montclair, county of Essex, andState of New Jersey, a citizen of the United States, have invented a newand useful Improvement in :Zuttons and a Metallic Fastening therefor, ofwhichthe following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming part of this 1ospecification.

This invention relates to buttons and analogous devices designed to beattached to gar nients by means of metal fastenings; and the inventionconsists in a button or similar con- I 5 trivance with a solid face,having a device to deflect or upset the bifurcated or other prongs of ametal rivet or fastener, in combination with a fastening device havingtwo or more sharpened prongs, consisting of vertical sec tions of ahollow cylindcrwith curved crosssections, and provided with a head, asis with greater particularity hereinafter shown, de scribed, andclaimed.

In the accompanying sheet of drawings,

Figure l is a vertical section of button or rivet-head and fastener inelevation; Fig. 2, a

vertical section of button and fastener when attached to garment; Fig.3, a plan of fabric, with cross-section of rivet; Fig. 4, an eleva- 0tion of fastener, showing throat d,- Fig. 5, a

plan of fastener with throat d,- Fig. 6, an elevation of fastenerwithout throat; Fig. 7, a

plan of fastener without throat Fig. 8, an

elevation of fastener with throat extending to head of same; Fig. 9, anelevation of unthroated rivet with prongs extending to head; Fig. 10, avertical scctionof button with separately-inserted deflecting device,and elevation of rivet.

The purpose of this invention is to combine with a button or rivet-head, or similar contrivance with a solid face, a metal fastening device which shall have two or more sharpened prongs, consisting ofvertical sections of a hol- 5 low cylinder with curved cross-sectionsand a head, so that the sharpened ends or points of the prongs can,without much effort, be forced through the fabric of a garment, or othermateria1,and then have its sharpened ends upset by a deflecting devicefixed to or within the inner surface of the shell of a button orrivethead. To properly combine a metal button or rivet-head withasharpene'ch pronged fastening device, I construct the button A or arivethead with aconical depression, a, formed in 5 5 its shell, or byplacing within the shell of the button or rivet-head any suitable deviceor contrivance that will answer the purpose designed, whether thiscontrivance form part of thebutton-shell or whether it be inerely inserted within the same. A fastening device, C, is next constructed, andthis device may have two or more prongs, 1), consisting of verticalsections of a hollow cylinder with curved cross-sections. The prongs,however, under all. circumstances, must be sharpened and provided with asuitable head, 0. This head may be integral with the metal of theprongs,which is preferable, or it may be attached to the base of theprongs in any suitable manner.

Now, when my button or rivet-head and its fastening device areconstructed substantially in the manner hereinbefore described, it isoperated by thrusting the sharpened prongs b through the desired fabricuntil the prongs protrude on one side of the fabric and their head 0shall lie snugly against the other side, a button, A, or rivet-head,withasolid face,being then placed so that the sharpened ends of the prongswill be received within the shell of the button or of the rivet-head,and in contact with the cone or other device, a. Suitable pressure beingapplied. to the button or rivet-head, the sharpened ends of the prongs bare upset or turned outward by the action of the cone or upsettingdevice in the buttonshell, which, entering between the prongs, curvesthem outward to an extent greater than the diameter of the orifice inthe button-shellthrough which they originally entered, thereby unitingthe 0 button or the rivet-head, as the case may be, .lirmly to its metalfastener, and tightly holding the fabric clamped between the head of thefastener and hub of the button or under surface of the rivet-head.

To facilitate the thrusting of the fastening device through the fabric,and at the same time to more perfectly. secure or fix the fasteningdevice to the fabric, it will be advantageous to form a space, it, at ornear the base of the sharpened prongs I), this space consisting,sul)stantjally, of a throat, into or across which will lie a strip ofthe fabric when the prongs are thrust through it, and this strip willact as a tie in conjunction with the fabric which is clamped between theinner surface of the head a and the button or rivet-head, as beforedescribed.

The advantage derived from making the sharpened prongs from a hollowcylinder is, that the curvature of the inner and outer surfaces of theprongs renders them stiffer and less liable to bend when thrust throughthe fabric, and causes them to upset or flare outward with greatercertainty when in contact with the de-' fleeting device than wouldotherwise be the case.

I do not desire to claim in this patent the particular construction ofthe fastening de- Charles E. Bates; but the Bates fasteners were merelyfiat-sided prongs stamped from sheet metal, and his buttons generallyhad perforated faces; but

WVhat I do claim as new, and ,desire to secure by Letters Patent, is-

1. The combination of a headed fastening device provided with two ormore sharpened prongs, consisting of vertical sections of a hollowcylinder with curved cross-sections, and a solid-faced button orrivet-head,with an upsetting device within the shell of the same, as andfor the purpose described.

2. In combination, a solid-faced button or rivet-head having an interiorupsetting device, with a metal fastener having two or more sharpenedprongs, consisting of vertical sections of a hollow cylinder with curvedcrosssections, a head, and a space or throat, d, as and for the purposedescribed.
